Regeneration of apical bony defects remains a significant problem in endodontic surgery. When a resorbable membrane is placed over a defect, it acts as a barrier between the defect and the overlying gingival tissue. This barrier membrane provides sufficient time for bone to regenerate while preventing the faster growing connective tissue from invaginating into the area. When new tissue replicates the structure and function of the lost tissue, then apical regeneration has occurred.
根尖骨缺损的再生仍然是牙髓外科中的一个重大问题。当在缺损处放置可吸收膜时，它可作为缺损与上方牙龈组织之间的屏障。这种屏障膜为骨再生提供了足够的时间，同时防止生长较快的结缔组织侵入该区域。当新组织复制丢失组织的结构和功能时，根尖再生就发生了。
